Can Sterile Neutrinos Exist?
Physicists have wondered if neutrino particles come in a mysterious fourth variety. Now new experimental findings complicate the question -- Read more on ScientificAmerican.com.....»»
The multiverse: Our universe is suspiciously unlikely to exist—unless it is one of many, says physicist
It's easy to envisage other universes, governed by slightly different laws of physics, in which no intelligent life, nor indeed any kind of organized complex systems, could arise. Should we therefore be surprised that a universe exists in which we we.....»»
Researchers discover way to reverse infertility by reducing HDL cholesterol
Houston Methodist scientists reversed infertility in sterile mice by reducing high-circulating cholesterol with a bacterial protein, showing further evidence that links high cholesterol to female infertility. This is a promising development, with one.....»»
A grasshopper-like soft material can jump 200 times above its thickness
Inspired by grasshoppers, the new material stores energy then uses it all at once. Enlarge (credit: Stefania Pelfini, La Waziya Photography) Superhumans don't exist in the real world, but someday you might see super robo.....»»
Ecuador to release sterile mosquitoes in Galapagos
Ecuador will release 100,000 sterile Aedes aegypti mosquitoes on its Galapagos Islands to curb dengue, Zika and chikungunya transmission, authorities said Friday......»»
It’s Time for a Flu Vaccine—for Birds
Avian influenza has killed millions of birds. Shots to prevent it already exist. Why isn’t the entire poultry industry using them?.....»»
Mathematicians have discovered the hidden patterns that exist within ‘chaotic’ crowds
As with many things found in nature, it’s not as random as it looks. A huge throng of people may seem chaotic. Think of the pandemonium of top-bill gatherings such as Coachella’s music festival or a Comic-Con convention, or even the be.....»»
The animals and plants that only exist in captivity—and why time is running out to restore them to the wild
It was April in 1981 when a party of four camped for two days and nights on the forested slopes of Mount Evermann, the central peak of Socorro, a volcanic island in the Pacific some 400 kilometers southwest of Baja California, Mexico. Their fruitless.....»»
Netwrix Privilege Secure eliminates standing privileged accounts across on-premises databases
Netwrix has released Netwrix Privilege Secure (formerly Netwrix SbPAM), which expands its zero standing privileges (ZSP) approach to databases to ensure privileged accounts exist for only as long as needed. “Netwrix Privilege Secure now elimina.....»»
Newly discovered form of salty ice could exist on surface of extraterrestrial moons
The red streaks crisscrossing the surface of Europa, one of Jupiter's moons, are striking. Scientists suspect it is a frozen mixture of water and salts, but its chemical signature is mysterious because it matches no known substance on Earth......»»
Protecting high seas off Chile"s coast depends on UN vote in New York
In international waters off the coasts of Chile and Peru, the ocean teems with plant and animal species—some do not exist anywhere else and many are endangered......»»
Newly discovered components of Dendrolimus pini sex pheromone
Beyond the seven mountains and forests, a hungry beast was stealing away. Does this sound like a fairy tale? In reality, such a beast does exist. It is the caterpillar of the nocturnal pine-tree lappet moth (Dendrolimus pini, L.), which feeds on pine.....»»
A method for analyzing tiny, complex crystals
The atomic structure of solid substances can often be analyzed quickly, easily and very precisely using X-rays. However, this requires that crystals of the corresponding substances exist. Chemist Professor Oliver Oeckler from Leipzig University and h.....»»
Scientific highs and lows of cannabinoids
Hundreds of cannabis-related chemicals now exist, inspiring researchers—and users. Enlarge (credit: Olena Ruban via Getty Images) The 1960s was a big decade for cannabis: Images of flower power, the summer of love and.....»»
Evolutionary trade-offs: Balancing genetic disease risks and pathogen protection
Certain genes can exist in different, functionally divergent variants in the individuals of a species. If they lead to clear differences, for example in a phenotype or susceptibility to disease, this is known in biology as a polymorphism. Typical exa.....»»
Study finds that choosing a lucky CEO means bad luck for the hiring company
Seneca, the Roman stoic philosopher, wrote that "luck does not exist." Modern managerial studies take the liberty of disagreeing. Luck exists in the form of events that are beyond the control of CEOs and firms alike. Movements in oil prices and the b.....»»
A new model for dark matter
Dark matter remains one of the greatest mysteries of modern physics. It is clear that it must exist, because without dark matter, for example, the motion of galaxies cannot be explained. But it has never been possible to detect dark matter in an expe.....»»
Tapbots readies ‘Ivory’ client for Mastodon as Tweetbot era unceremoniously ends
The dust continues to settle following Twitter’s decision to cut off third-party apps from its API. Twitter’s poorly communicated decision means that apps like Twitteriffic and Tweetbot can no longer exist. In light of that, Tapbots has publishe.....»»
Antarctic icebergs still exist today where 1700-era sailors spotted and tracked them
A new study comparing observations of large Antarctic icebergs from the 1700s with modern satellite datasets shows the massive icebergs are found in the same areas where they were pinpointed three centuries ago. The study shows that despite their rud.....»»
Final results from the STEREO experiment reject sterile neutrino hypothesis
After several years of operation, the STEREO collaboration published the final results of their antineutrino studies. With their data, the researchers excluded hints for the existence of sterile neutrinos, an additional neutrino state expected in man.....»»
Researchers detect fluoride in water with new simple color change test
Environmental contaminants like fluoride, lead and pesticides exist all around and even within us. While researchers have simple ways to measure concentrations of such contaminants inside lab environments, levels are much more difficult to test in th.....»»
